SSL certificates can be used to set up client authentication and encryption of your alarm data. Currently the only supported method of serving the AlarmDecoder over SSL is through ser2sock, though support is destined for AlarmDecoderGUI in the future.
Generating a certificate for the Certificate Authority
We use an intermediate certificate known as a Certificate Authority in order to provide an authentication mechanism for the AlarmDecoder devices. This allows you to restrict access to the service to only those certificates that have been signed by the CA. This also allows you to revoke client certificates or even regenerate the CA certificate itself should it get compromised.
